Abstract
A battery pack charging and discharging protection system comprises a battery pack and a power input controlling circuit connected with the battery pack. The system has a voltage regulator unit and a charging and discharging protection unit. The protection unit includes a coupling wake-up circuit, a power-off acceleration circuit, an MCU self-locking circuit and a button detection circuit. The coupling wake-up circuit is connected with the power input controlling circuit. The power-off acceleration circuit is connected with the coupling wake-up circuit. Compared to the conventional technology, the present invention adopts single-wire compatible communication and coupled wake-up mode to achieve the autonomous power-off of the battery pack in time, avoiding over-discharge of the battery caused by the long-term self-consumption of the battery pack.
